    Abstract: A process for producing an epoxidized diene polymer which comprises: dispersing or suspending a diene polymer (C) having a particle diameter in terms of sphere diameter of 0.05 to 20 mm either in a medium (A) in the presence of powder particles (B) insoluble therein or in a water medium in the presence of a phenolic stabilizer and/or phosphorus compound stabilizer; and epoxidizing the diene polymer (C) in the dispersed or suspended state with an epoxidizing agent. Thus, an epoxidized diene polymer having excellent thermal stability is obtained. By the process, the epoxidation of the diene polymer (C) in a solid state and the production and purification of the target polymer are economically conducted. The process is free from various problems associated with the epoxidation of a diene polymer dissolved in a solvent.

    Abstract: PROBLEM TO BE SOLVED: To provide a sensitive film containing a polymer where an anion ion exchange group is subjected to covalent bond, and an anion ion selective electrode that is highly selective using the reactive film and is highly reliably in measurement. SOLUTION: In the anion ion selective reactive film containing the polymer of anion exchange properties, epoxidation diene-family block copolymer is used as one raw material constituent for the polymer with the anion ion exchange properties. Further, by forming the epoxy group of the epoxidation diene-family block copolymer into hydroxyl group, hydroxyl group is subjected to direct covalent bond to the polymer with the anion exchange properties. The anion selective electrode uses the anion selective film.
